The Kreitler Challenger Rollers is an ideal method of resistance training in compact, portable package. For almost 40 years, Kreitler has been producing some of the smoothest and quietest rollers on the market. Some would say Kreitler Rollers are the "Rolls Royce" of rollers; beautifully machined while offering the best combination of resistance, cost, and portability. Kreitler rollers will simultaneously allow you to increase your cadence, increase power, and improve your form all while helping you develop better balance and technique. Regardless of your current skill level, there is a Kreitler roller system that will help you become a better cyclist.
Kreitler rollers are offered in several different drum diameters; as the drum diameter decreases, the resistance of the roller system will increase due to the bearing and tire friction. At any given speed, a smaller drum will need to rotate at a faster RPM than larger drums, causing more friction in the bearings which ultimate producing higher resistance.
The Kompact series of Kreitler rollers combine the 15" alloy drums with the Kompact frame to provide a smaller, low-profile set of rollers that are ideal for transporting, making it the ideal choice for those looking to warm up before races. This particular Kreitler Kompact roller system uses alloy end caps, which are longer lasting and create more momentum in the rollers compared to the polycarbonate end caps. The Kreitler Kompact Alloy 3.0 Rollers provide 40% more resistance compared to the Alloy 4.5 while the Kompact Alloy 2.25 rollers provide a whopping 90% more resistance compared to the 4.5 models.
